Question

Which set of side lengths does not represent a right triangle?

a. 7 inches, 10 inches, 16 inches
b. 6 inches, 8 inches, 10 inches
c. 5 inches, 12 inches, 13 inches
d. 3 inches, 4 inches, 5 inches?

Answer 1

The answer is A because √(7² + 10² ) does not equal 16, but it is about 12. The pythagorean theorem states that in a right triangle a² + b² = c², and it doesn't fit the equation. Hope this helps!
